SPECIFICATION forming part of Letters Patent No. 785,871, dated March 28, 1905.

Application filed April 9, 1904. Serial No. 2OZ,368.'

To all whom, it may concern:

Be it known that we, J our: T. GLAZIER and CHARLES C. (ILAZIER, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in R0- tary Heads, of which the following is aspecification.

The object of this invention is to providea rotary head forstand-pipes used in automatic fire-extinguishing: equipment both inside and outside of buildings and for use in connection with lawn and other sprinkling hose whereby the pressure of the water will cause the head to rotate and thoroughly distribute the water.

The object also is to provide adjustable tips the direction in which the water is thrown therefrom may be regulated by changing the position of the nozzles.

The further object is to provide a valverelease which will open at a low temperature above the normal by the melting of a tie which fuses ata low temperature.

We accomplish theobjects of the invention by the mechanism illustrated in the.accompanying drawings, in which- Figure 1 is a side elevation of our invention for stand-pipe and fire extinguishing purposes; and Fig. 2, a longitudinal vertical section of same, showing changed positions of some of the parts in dotted lines.

Like characters of reference indicate like parts throughout the two views.

1 represents a stand-pipe in which there is water under pressure. 2 is a goosen'eck extension of pipe 1. Its outer end forms a seat for the valve 3. Screwed to the outside of the end of the extension 2 is the elbow pipe-section 4, on the free end of which the rotary head is mounted. is perforated, and around the perforation is the threaded flange 5 on which the cap 6"is screwed. The cap has the diametrically opposite lugs 7 and 8. The stem of valve 3 passes through the perforaionof the wall and through The wall of pipe 4- the cap. It has the head 9, against which is placed a bar 10, which has one of its ends connected with lug 7 of the cap by means of the bolt 11 and the other end connected with lug8 by'means of the strap 12. The strap is hooked to the bar and lug to prevent accidental displacement, and the lug and bar will preferably have notched seats to prevent lateral displacement of the strap. The strap will be of a metal or composition which melts at a low temperature and when melted will release the bar 10, which releases the valve and allows 'it to be opened by the pressure of the water in the stand-pipe. The bolt 11 is passed into a slot in the end of the lug 7, so that when the bar 10.is released the bar and bolt will be free to drop down clear of the-stem and holding-lug 7.

An externally-threaded sleeve'13 is slipped over the end of the pipe-section 4, and then to form the be a separate ring brazed, or otherthe end of the pipe is swaged out flange let, or the flange may which is screwed, soldered,

wise securely fastened to the end of the pipe 4 to prevent theremoval of the sleeve 13. The innenedge of the flange 14 ishalf-round, as shown at 1-5, to-insure a water-tightfit be- 'hasa threaded opening in the side, bywhich it is screwed fast to the threaded sleeve 13. The walls of the body have the perforations 21, which deliver water in thin streams in as many different directions as there are variations in the direction of the holes. The ends of the body 16 are externally screw-threaded to receive the internally-screw-threaded sleeves 17 17, each of which latter have the inside flanges 18. Through the aperture between the fianges the tips 19 are passed. These tips have flanges 2O attheir inner ends, which areengaged by the flanges 18 of sleeves 17. The tips are bent, as shown, so they will deliver laterally instead of longitudinally. The tips are locked in a given position by tween it and the packing-ring 16" of brass or the flange 18 and end of the body.

screwing the sleeves 12 in on the body 16 till i the outside and a fusible tie for holding said their flanges are tignti 1 impinged between By loosenthe sleeves they may be set to throw water at angie and there-fore xveli adapted tn zeeeh up into the comb 01 e, gebie-root' down t0 the iieer 0: in any desired direction.

Fer iewn-snrinkiing the valve end geeseneek wiiihe emitted end connection with the hese Wiii be made direct to pipe 4t, the letter being either with or without the bend at its iewei' end.

The head may be made Without the perfoit so desired.

Having thus fuiiy described our invention, what we claim as new, and Wish to secure by Letter- Patent, is-

Tn A rotary heed having rotary edjiistebie,

dieeherge ends, a one-piece body cennecting 2e 1 endsesuppiyplpeieedlng into said body, Bead body hevmg 1 ert0s*at10ns opposite the meuth of the, supply-pipe, an internal valve in the suppifY-pipe having" a stem extending to stern.

2. A rotary head having rotary adjustable discherge ends, a one-piece body connecting seid ends, esuppiy-pipeieedinginto said body having an elbew-bend, a valve seated against an end of said elbow having a stemterminating outside of the pipe, and means held by e fusible tie for holding said stem.

3. A pipe having an end seller with halftween the collar and the sleeve and a rotary heed secured to seid sleeveseid head having rotary adjustable dischargetips.
